Study design (if review, criteria of inclusion for studies)
Double-blind, randomized, placebo controlled crossover study
Participants
Adolescent and adult patients with cystic fibrosis and exocrine pancreatic insufficiency. A total of 35 patients were randomized into the study and 22 patients completed both treatment periods.
Interventions
A novel microbial lipase (NM-BL) in a liquid formulation or placebo for 1 week as replacement for the usual pancreatic enzyme formulation.
Outcome measures
The coefficient of fat absorption was evaluated as the primary endpoint. Symptoms and adverse events were evaluated as secondary endpoints.
Main results
During treatment with NM-BL, the coefficient of fat absorption was significantly greater (72.7%) compared with placebo (53.8%) with a difference between groups of 18.8% (P < .001). Subjective assessment of stool fat and stool consistency also improved under treatment with NM-BL. Adverse events were mostly gastrointestinal in nature and were more common in the group receiving NM-BL.
Authors' conclusions
Currently available pancreatic enzyme products are limited because of the lack of liquid formulations and being largely porcine based. The novel microbial lipase NM-BL was safe and effective in this short term trial. The trial provided clinical proof-of-concept for this novel microbial lipase as a treatment for EPI in CF. A larger phase 2 dose ranging trial is warranted.
